Intrinsic; inborn (8)
I believe the answer is:
inherent
I believe this is a double definition.
'intrinsic' is the first definition.
(similar in meaning)
'inborn' is the second definition.
(thesaurus)
(Other definitions for inherent that I've seen before include "constitutional" , "Innate, natural" , "Underlying - integral" , "Inborn or intrinsic" , "Existing permanently in something" .)
